FABRIC-WINDING MECHANISM.

Application filed October 31, 1921. Serial No. 511,721.

T0 (127. whom it may concern;

Be it known that 1, ROBERT Enrnnn, a citizen of the United States ofAmerica, and a resident of WVeehawken, county of Hudson and State of NewJersey, have invented certain new and useful Improvements inFabric-Winding Mechanism, of which the following is a specification.

The present invention relates to fabric winding mechanism ofembroidering machines or the like and has for its object to provide animproved construction whereby the fabric roller can be readilydisconnected from the feeding mechanism and be turned by hand to wind upthe fabric to be embroidered or remove the finished embroidery from theroller.

It has been found that with the large embroidering machines generally ofabout 15 yards length the winding up of a piece of fabric and theremoval of the finished fabric from the fabric roller by means of thefeeding mechanism is objectionable because when the fabric during eitherof such operations becomes caught the operator is unable to discoverthis, since the resistance offered to the feeding mechanism by thecaught part of the material is too small to be noticeable and cautionthe operator of any irregularity in the operation, with the result thatthe material is torn. Therefore,

it is preferred to wind up and 0E the ma-v terial by hand which enablesthe operator to feel with his hands the slightest resistance and removethe same before any damage occurs. But with the winding mechanism ofordinary construction the turning of the fabric roller by hand is verydifficult, if not utterly impossible, and can be done only very slowlyentailing considerable loss of time owing to the friction between themeshing gears of the winding mechanism, and to some parts, such asratchet and pawl, that have to be disengaged to permit the roller toturn in the reverse direction, being not very easily accessible.

These difficulties are overcome according to my invention by arrangingone of the gears of the winding mechanism on a longi tudinallydisplaceable shaft so that whenever the roller is to be turned by handthe said gear can be simply moved out of mesh with the other gearthereby releasing the roller to be free to be turned in both directions.

This invention will be more fully understood by reference to theaccompanying drawing in which similar characters denote correspondingparts and in which Fi g. 1 is a front elevation of the fabric windingmechanism of an embroidering machine with some parts shown in section,and Fig. 2 an inner end view thereof with the fabric roller removed.

In the drawing a denotes the fabric frame and b the hearings in which isrotatively supported a shaft. 0. The shaft 0 extends outwardly throughthe frame and on its projecting end c carries a gear (Z suitably fixedthereon. The gear (Z is provided centrally with an oblong projection eof rectangular shape to engage between two ear like members f projectingfrom the end of the fabric roller g. The opposite end (not shown) of theroller may be constructed and supported in a similar way. The end 0 ofthe spindle 0 is extended to project tirough a central bore 9 into theroller g.

In bearings h of the frame is supported a second spindle 2' parallel tothe spindle 0 which also is extended to project outwardly from the frametoward the roller 9. Qn the outer end of the spindle is fixed a smallergear j which is capable of meshing with the larger gear (Z to transmitmotion to the roller for feeding the latter during the embroideringoperation. The spindle i also carries the ratchet wheel 76 with whichcooperates the pawl Z (Fig. 2), said ratchet and pawl constituting partof the roller feeding mechanism. The spindle a is so supported in thebearings 73. as to be longitudinally displaceable. The ratchet wheel isadapted to be held, against axial displacement by its hub 7.1 beingmounted between the lateral hearings 1 and is rotatively connected tothe shaft 6 by a key on engaging a longitudinal groov 2" in the spindlei.

Owing to the spindle z'being displaceable longitudinally it is possiblewhenever it is desired to wind a piece of fabric around the roller orremove the finished goods from the latter to simply pull the small gearout of mesh with the larger gear into the position indicated by dottedlines (Fig. 1) thereby releasing the roller 9. A stop 0 in form of a pinor the like may be provided on the spindle i which when the spindle isdisplaced will abut against the hub 72 and prevent the spindle frombeing removed entirely from its bearings.

What I claim is:-

1. In a fabric winding mechanism for embroidery machines or the like,the combination with the fabric roller, rotary shaft, ratchet and pawlcooperating with the latter, of a pair of intermesh'ing gears forfeeding-said roller during the embroidery operation, of which gearsoneis mounted on said rotary shaft and operatively connected to saidroller, a longitudinally .movable'shaft on which the second of saidgears is fixed,

said shaft "having ,a longitudinal groove, a key in said groove toengage the ratchet "mounted on said second shaft and a stop for limitingthe longitudinal displacement of said second shaft.

2. In a fabric winding mechanism for ein brolderlng machines or thellke, the combnation with the fabric roller, of arotary shalt, a gearfixed on said shaft and having fixed to said displaceable shaft to meshwith said first named gear, said last named gear being capable ofbe-ingbrought out of mesh with said first named gear by displacing said secondshaft topenable the turning of th fabric roller by hand. 7 V
